Hello,

I'm trying to refresh my web page with a webmethod because I want to update an oracle databases and refresh a table in my web page.
I'm truing to do it with jQuery ajax() but I don't know "how to make a postback". DO you know please ?
This is my current code :

JavaScript

$.ajax({
        type: "POST",
        data: "{ request : " + JSON.stringify(listeIdEntiere) + "}",
        url: "Test.aspx/doAssignation",
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (msg) {
            alert(msg.d);
        },
        error: function () {
            alert("BAD");
        }
    })

C#

[WebMethod]
public static string doAssignation(string request)
{
    return request;
}

Requirement is not clear. If you are using a Web Method that means you are using ajax functionality. Then you can return what ever value you want from that method and in success method you can assign that to the table. So, the table will have new values.

What is the problem ? Please explain more about the requirement.

I don't know for the moment because a static WebMethods can't access to Session and I need Session to do my work :'(

Does your test.aspx page exist?, should be a asmx page

You should call the page directly and make sure it works first, you should get a textbox that you enter the value into.

Then work on the jquery side

Solution 1

In your success function of jQuery's .ajax() method, add

JavaScript

location.reload(true);

This JavaScript will cause the page to reload. It won't postback, but from what you described you just want it to refresh and not postback. They are different.

HI,
TO do this you have to employee a ashx handler .
Inside the ashx handler call the web service.
write in to the response stream of the http request.
Call the handler with the help of Jquery AJax
You will get response in the JQuery ajax Success.
why i suggested the handler is that you mentioned that you also want to make use of session,if you implement an inter face called

C#

IReadOnlySessionState

then you can use session in http handler.
